Atomic layer deposition (ALD) is a very attractive ultra-thin film deposition technique. With the feature size of IC industry continues going down, ALD has received more and more attentions for its accurate sub-nanometer thickness control as well as superior uniformity and conformality. The further development of ALD technology emphasizes on both process and equipment innovations. A single-wafer bottom-heated reactor is constructed successfully, and the Al2O3 is deposited with ~2% uniformity across a 4-inch wafer. Furthermore, the gas delivery system and heating devices are studied by the combination of ANSYS simulation and experiments. These parameters that influence the uniformity and conformality of deposited films have been further optimized to obtain better performance. As a result, a new reactor with showerhead gas delivery and radiation heating system is designed.

ABSTRACTAtomic Layer Deposition (ALD) is an emerging ultra-thin film deposition technique for advanced microelectronics applications. Enabling features of ALD are precise control over film thickness, excellent conformality and relative insensitivity to wafer size. Additionally, ALD allows interface and film engineering that can be utilized to maximize device performance within the minimum feature size requirements. This paper reports on the compositional, structural and electrical properties of engineered Ti-Ta-N composite films grown by ALD at 360°C. For a wide range of composition these Ti-Ta-N films exhibit resistivity from 500 to 2000 μω-cm, high density, and 100 % step coverage. Additionally, the ability to control texture by changing film composition is established. Based on experimental results, an approach to grow Composite Engineered Barriers by ALD (CEBA) is described that could provide a solution to the challenging barrier requirements.
